Gosh, vis, thanks. You really opened my eyes there. I didn't know. I did research the lens but I didn't find that information. I already felt good about buying the lens. Thanks to you, now I'm feeling GREAT!

I do have many lenses, possibly too many, but in few years I will massively reduce my collection.
No worries, I will announce it here

I don't have too many lenses but I do consider downsize my collection(less and less time for some of them). It will be a nice idea to keep the best ones and rarest ones only._________________My Flickr on street photography

What does that even mean? Too many lensess? I have some I would relinquish but, far more I covet: minolta md 58mm 1.2,topcon 85mm 1.8 zeiss galore.........my most recent samples with the schneider tele arton 90mm f4 dkl with pixco helical on a7ii (I think you will like....)_________________photos are moments frozen in time

Unfortunately I have to agree to that _________________Klaus - Moderator

A nice example in PK mount of one of the classic 17mm for a reasonable price - most often these or the tamrons bid up towards £100+. First impressions good - I'll post some pics.
Lens pic with my sigma miniwide 28mm.

I already owned a (used) copy of this lens and never expected to own a second copy. But when this lens popped up at the price it did, I was not able to resist purchase. Also was pleased to obtain the brand new, correct, hood, and the two new cases. The new hood and case alone would probably sell for between ten and twenty US dollars.

There seem to be two main varieties of the preset t-mount 35mm lenses: one type has the aperture rings at the front of the lens, the other at the rear by the mount. I reviewed a vivitar branded one of the latter on PF. Yours guardian looks more like the one in the P&B brochure._________________pentax ME super (retired)

That one reminded me of a lens i've had for some time, it came with a Minolta SR7 which i think i bought from a forum member. Never used the lens though.....
it's branded Galaxy.

That Prinz is possibly the worst prime lens ever made, optically it is terrible and they often fall apart, cheap, nasty, horrid._________________I don't care who designed it, who made it or what country it comes from - I just enjoy using it!

From memory, I had one where the optical block just fell out one day, and it had very severe field curvature so that the edges were never in focus if the centre was and this was on an APS-C sized sensor so it would have been worse on 35mm/full frame.

There are 3 copies in this pic, branded Crystar, Photax and Prinzgalaxy:

That Soligor lens with the "KA" serial looks the same, apparently there are versions with the aperture ring at the mount side. But according to the Savazzi site the optical layout is exactly the same......
For such a common lens (which i did not know, i had never seen another one!) there are indeed quite some variations and names.....
